Sound Randomizer 1

[eladi]

Hi,

A friend composed some sound for my website. We split it into 11 pieces in a way that they can be played in random order. For now I'm working on the randomizer, therefore I have the sounds imported (I'll do the external loading later) and did the linking settings including id.

first: i read somewhere that i can create only 8 sound objects. is that ture? if so, i will have him got the piece into 8 parts not 11.

second: i think i got a way i can play them at random order now. but for some reason, there's an error. i trace the random numer and in which soundCompleted function it is generated. nevertheless, it always just plays track 7, although the trace comes from another 'soundCompleted handler'. here's the code. i know, this might be done more compact, but anyway:

firstSound = new Sound();
firstSound.attachSound("sound1"
secondSound = new Sound();
secondSound.attachSound("sound2"
thirdSound = new Sound();
thirdSound.attachSound("sound3"
forthSound = new Sound();
forthSound.attachSound("sound4"
fifthSound = new Sound();
fifthSound.attachSound("sound5"
sixthSound = new Sound();
sixthSound.attachSound("sound6"
seventhSound = new Sound();
seventhSound.attachSound("sound7"
eighthSound = new Sound();
eighthSound.attachSound("sound8"
firstSound.start(0,1);
firstSound.onSoundComplete = function() {
auswahl = (random(9));
trace("Von firstSound " + auswahl);
firstSound.stop();
switch(auswahl) {
case 1: firstSound.start();
case 2: secondSound.start();
case 3: thirdSound.start();
case 4: forthSound.start();
case 5: fifthSound.start();
case 6: sixthSound.start();
case 7: seventhSound.start();
case 8: eighthSound.start();
default: firstSound.start();
break;
}
}
secondSound.onSoundComplete = function() {
auswahl = (random(9));
trace("Von secondSound " + auswahl);
secondSound.stop();
switch(auswahl) {
case 1: firstSound.start();
case 2: secondSound.start();
case 3: thirdSound.start();
case 4: forthSound.start();
case 5: fifthSound.start();
case 6: sixthSound.start();
case 7: seventhSound.start();
case 8: eighthSound.start();
default: firstSound.start();
break;
}
}

.
.
.
it continues on until eighthSound similarly. The code is copy&pasted. I also checket the .Sound.stop() functions, especially in seventhSound, but it seems to be ok. here:

seventhSound.onSoundComplete = function() {
auswahl = (random(9));
trace("Von seventhSound " + auswahl);
seventhSound.stop();
switch(auswahl) {
case 1: firstSound.start();
case 2: secondSound.start();
case 3: thirdSound.start();
case 4: forthSound.start();
case 5: fifthSound.start();
case 6: sixthSound.start();
case 7: seventhSound.start();
case 8: eighthSound.start();
default: firstSound.start();
break;
}
}

Would be greatful for help.

You start the first sound... and stop it to randomly set up on a second sound to be played, but you never seem to be starting that randomly selected sound? Regards,

Isn't that what the switch() function that i set up is supposed to do?

How about this? Much shorter....

//set up sounds in an array for convenience

soundFile = [];
for (var i = 1; i<9; i++) {
	soundFile[i] = new Sound();
	soundFile[i].attachSound('soundFile'+i);
}

//generates a random number between 1 and 8

function randomNum() {
	return Math.floor(Math.random()*8)+1;
}

//main function

function generateRandomSound() {
	randomSound = soundFile[randomNum()];
	randomSound.onSoundComplete = function() {

//loop

generateRandomSound();
	};
	randomSound.start();
}

//go

generateRandomSound();

stop();

This works with files on my hard drive but I haven't tested it online - the only drawback is that you don't know exactly what order the sounds will load in.

//set up sounds in arrays

soundFile = [];
loadedSound = [];
var numSounds = 4;

//load sounds

for (var i = 1; i<=numSounds; i++) {
	soundFile[i] = new Sound();
	soundFile[i].onload = function() {

//assign sounds to second (playing) array as soon as they're fully loaded

loadedSound.push(soundFile[i]);
	};
	soundFile[i].loadSound('sounds/sound'+i+'.mp3');
}

//generates a random number between 1 and whatever's loaded

function randomNum() {
	return Math.floor(Math.random()*loadedSound.length)+1;
}

//main function

function generateRandomSound() {

//select from sounds which have loaded

randomSound = loadedSound[randomNum()-1];
	randomSound.onSoundComplete = function() {

//loop to new sound

generateRandomSound();
	};
	randomSound.start();
}

//go

this.onEnterFrame = function() {
	if (loadedSound.length>0) {

//wait for the first sound to load then start looping through them

generateRandomSound();
		delete this.onEnterFrame;
	}
};

stop();
